Technology and Science Unite: Solving Crimes Essay

Forensics has changed the way our criminal system works now. A lot of cases are being solved because of the development of forensics. Even cold cases are being brought up to the light to be investigated again and a good percentage of the cases are being solved and criminals are being brought to justice. The green river killer is one case that really got me intrigued into forensics and I got mesmerized by the techniques that are being used to catch murderers and other crimes being committed. The green river killer had an interesting childhood that led him to be a serial killer. He committed multiple murders on prostitutes and left there families with agony and pain. But advances in DNA ultimately led to his demise, police officers were able

Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with

“Forensic science has become in the early 21st century what the space race was in the 1960s- an accessible and inspiring (Gaensslen) into the world of science” (Gaensslen ix). This may be true but forensic has not always existed forever. Many people began hearing about forensic science during the 1990s when many of crime shows became popular. In actuality forensic science goes as far back as ancient China. Sculptors used fingerprints to identify their artwork from that of others. This may not be what forensics has evolved into but it had to begin somewhere. The first text reference of forensics first showed up in Hsi Duan Yu, which was published in about 700 CE (Hunter 18). It noted that many bodies have various characteristics that make them different. Many of the early forensic advances took place in the 1700 and 1800s. In 1784 the physical matching of evidence began. It was first used in the case of John Toms to link him and a piece of pistol wadding to a murder (Lotter). From then on forensics began to grow exponentially. “A major landmark in forensic science, the discovery that

Police databases and offense reports have been improved by technology and have enhanced law enforcement organizations’ ability to function. One type of police database is a fingerprint databases that

As human overpopulation increases, there will be a lack of resources and basic necessities that will become scarcer elevating crime rates. The broad field of forensics has numerous jobs that specialize in a specific duty. It provides and analyzes evidence in laboratories or offices that helps both state and local police departments solve crimes. As technology advances it also aids in the advancement of forensics. Forensic Science Technicians are required to have a variety of distinctive skills to assist in criminal investigations.

crime scene could be analyzed and compared with a sample from a suspect. A match could place

Beginning in the mid-1980s, the development of DNA analysis technology has revolutionised the field of forensic science within the criminal justice system. As the refinement of procedures and technology continues, even minute samples of biological material (including blood, saliva, semen and skin cells) are able to be analysed and used to link or acquit perpetrators of crimes. (Whitney, R n.d.)

DNA forensics can also narrow down suspect pools, exonerate innocent suspects, and link crimes together if the same DNA is found at both scenes. However, without existing suspects, a DNA profile cannot direct an investigation because current knowledge of genotype-phenotype relation is too vague for DNA phenotyping. For example, a profile from a first time offender that has no match in any database may give the information that the criminal is a left handed male of medium stature with red hair and freckles. It would be impossible to interview every man who fits that description. However, with available suspects, DNA forensics has many advantages over other forms of evidence. One is the longevity of DNA. Although it will deteriorate if exposed to sunlight, it can remain intact for centuries under proper conditions (Sachs, 2004). Because DNA is so durable, investigators can reopen old cases to reexamine evidence.

Behind every court case there’s a train of forensic science evidence and research. Forensic science is the application of scientific principles of criminal justice. In many court cases a forensic scientists is the one on the scene collecting finger prints, photos, blood samples and other evidence. Unfortunately one of the controversial issues in the forensic world is the evidence and its lack of verification of its reliability. In the field of forensics there are issues in finding proof in generating conclusion, fundamental knowledge to solve problems, and the whole false memory defense in the court. These issues can be solved in many ways like extensive research, preparation and training. These issues

Do you remember when our policemen had to ride around on horses to get from place to place? Most probably have heard about it, but think to themselves ‘all I have ever known as police cars and motorcycles’. For over a century the world has been making advances with technology in all areas of life, and the field of criminal justice has not been an exception to this technological advances. These advances in technology has taken the criminal justice field a long way from riding a horse bareback to driving armored cars. These advances along with many others have almost completely changed how things are handled in all aspects of the law.

A segment of the Forensic Science in the Criminal equity organization that the vast majority acquainted with these days, however, few individuals know how this particular science came to be. Overall, legal science is intended to utilize experimental standards to clarify obscure parts of a wrongdoing. Through the utilization of uncommon tests and lab gear that permits researchers to recognize decisively different parts of a bit of confirmation in an illegal behavior. On the off chance that you occupied with finding out about how this procedure came to fruition, you have to peruse the recorded data underneath. Here is a brief history

For example it has search capabilities, electronic image storage, and can exchange images of fingerprints and responses. The IAFIS is a home to fingerprints and criminal histories of 70 million subjects. Now, the IAFIS is maintained by the FBI or the Federal Bureau of Investigation. To be recorded into the system you could have employment background checks or firearm purchases that would cause you to be permanently recorded in the system. The person who is in charge of the IAFIS database is the Section Chief David Cuthbertson which is in the Programs Development Section. The FBI uses this database to find possible criminals if they find their fingerprints at a crime. They can run this information through the information and the IAFIS will pop up with information on that person. They can then use this information to their advantage and bring this person in for

With regard to the US, where social science and STS research have, focused less on forensic databases and more on the production of expertise and evidence in court, Jay Aronson provided a historical account of the early practices, the scientific and legal controversies, and the ultimately successful acceptance of forensic DNA evidence in court in 2007. Another particularity of social science and STS research in this domain is that it has so far mostly concentrated its “high end” forensic technologies, namely those which received a lot of public attention because they were new, because stakeholders in the criminal justice system struggled to determine the parameters of scientific reliability and admissibility, or because they were prominently featured in the media. While the use of DNA analysis for police investigations and forensic casework dates back to the late 1980s, the second half of the 1990s marked the beginning of the quest to render DNA profiles systematically and routinely searchable and minable by setting up centralized DNA databases in many countries around the world. A DNA molecule is a long, twisting chain known as a double helix. DNA looks pretty complex, but it's really made of only four nucleotides: Adenine, Cytosine, Guanine, and Thymine. These nucleotides exist as base pairs that link together like a ladder. Adenine and Thymine always bond together as a pair, and Cytosine and Guanine bond together as a pair.

In the 1540s, Ambroise Paré , a French surgeon, began examining how gunshot wounds and arrows impacted internal organs. He published a book, and that book is considered the beginning of modern forensic pathology (Martinez, 2012). In

Forensic science involves the use of science to solve criminal and civil crimes but mostly lies on the side of criminal investigations. It makes it possible to identify the criminals based on the DNA traces they leave behind. It involves analyses of blood, DNA and other evidences and later on uses the findings as evidence in the court of law. It helps in solving the various crimes in the world and this has been the greatest contributor to the growth of the sector. Cases that were previously considered impossible due to lack of evidenced tracing to the victim can now be solved using forensic science evidences. The essay aims at analyzing the different aspects of forensic science that are used in the process of solving criminal activities. It will also look at the different cases that forensic science was used to solve crimes in a court of law.
